. JQINT FOR INTERSECTING METALLIC MEMBERS.

To all whom it may concern:

Be it known that 1, WILLIAM E. ULRICH, citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Jointsfor Intersecting Metallic Members, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in metallic framing, more especially window sash or like structures, shown in the accompanying drawings and more particularly set forth. in the following specification and claims.

The object of my invention is to provide a locking joint for intersecting mullions, and the sush -frame, in which the regular commercial shapes of iron are employed to form the cross bars and frame of the structure,- the resulting sash being'exce edingly strong and symmetrical in'appearance.

A further object is to provide a'joint simple and inexpensive in construction and one in which both intersecting members are provided with continuous unbroken portions alternately overlapping the point: of intersection, thereby providing a structure interlocked in such a manner as to insure against separation at the joint and adapted to 1r.e' sist all strains it may be called upon to bear. In the drawings accompanying this speci- 'fication: Figure 1 is a fragmentary perspec tive view of a pair of intersecting cross mullions as they appear assembled and in locked relation. Fig. 2 is a fragmentary perspective view withparts broken, away; indicating the manner of engaging the Web ofjanintersecting member with the web of the cross member. Fig. 3 is afragmentary perspective view with parts broken away of one of the mullions engaged with the frame of the sash. Fig. 4 is a fragmentary perspective view of an intersecting mullion engaged with the frame of the sash. Fig. 5 is a frag-v mentary perspective view of the sash frame with the web portion punched to receive the projecting end of the cross mullions. Fig. 6 is a, detail perspective view of the end of the web and head or flange of a crossmul- Specification of Letters Patent.

View of the web of a cross mullion punched 1 and spread apart to receive theweb of the intersecting mullion, as indicated in Fig 2.'

Referring now to the letters placed upon-the drawings :A is the frame of reference of the sash; B the-vertical sash bars or muls lions.

C indicate the horizontal mullions formed of a web portion 0 and a head or flange portion 0 separate from the web portion. The web portion C is punched as indicated at c in Fig. 7,'to receive the web of the inter-- secting mullion B,the web being divided at cin order that the wall surrounding the aperture may spread apart for the receptionof the mullion B, in turn notched at b, b, to-

flange of the mullion B is also cut away as indicated at B',-the web being punched: as shown at B for the passage of the head or flange G of the mullion C. 5

As shown in" F igl 5, the frame A is punched at A to receive the projecting-ends; of the mullion C,the ends of the web and head portion of the mullion C being formed with projecting tongues O and (3*, respectively, which after insertion in the frame are riveted thereto. The ends of the verreceive the wall 0 c of the web C. The f all) tical mullions are also provided with a projecting tongue B set in: apertures provided in the frame and rivetedthereto, as indicated in Fig. 8.

Having denoted the several-parts by ref erence letters; the construction and manner of assembling" the same will be; readily understood. i

In order to place the webC in condition- I I to receive the web of the intersecting member B, the divided bridge Wall at the end of the aperture '0 is first spread apart as previously stated. The web of the intersecting mullion may then be inserted as indicated in Fig. 2;the web C is then restored to its initial condition thus connecting the intersecting webs of the mullions B and C together. The flanges c of the mullion C are next inserted through the apertures I 2 provided in the mullions B, andspot welded if .fienge portion of the T-shaped' member extending continuousiy and unbroken through the web andfiange of the first named meinn Ei e desired to the webs,the ends of the nmilions B and C being riveted to the frame A as indicated in Fig. 8.

Having thus described my in vention,'-whet I claim is:

l. The combination. of two intersecting muliicns one of mullions having its web notchedend portions of its flange removed for the passage of the intersecting muiiion, the intersecting niuilion constructed with an independent web and flange portion assemb'ied to form 9. 'T-shaped bar, the web portion being slotted to receive the web of the first named inuiiion, the weii bridg; ing the slotted portion being divided at one end or" the siot whereby said web may be bent to receive in the siotthe web of the first named nmiiion, the bent portion of the web being subsequently restored to its initial condition whereby the webs of said cross members are interlocked, and the independent' flange portion of the T-sheped. her, in tersecting the first named nuilion through the opening therein provided for its passage.

'2, The combination of two intersecting niembers one of which is cross-shaped in section,- said cross-shaped her having portions of its'flenges and web removed for the passage of an intersecting member, the in tersectingmembercomposed of two sep arete bars assembled in T-shaped form, the

the'independent flange portion slot of the cross-inuihon above the separate her the web portion of the T-shaped incinber being slotted end the wail at the end of the slot divided whereby the web iney bent to receive in the slot the web of the tersecting her, said bent web p'rtion b subsequently restored'to its orig ns condi tion to ciose around the web of the intersect ing member whereby they are interlocked. 3. The combination of 'two 'interst mniiions one of said muilions cro i in section having portions of its flan s removed and its web notched and siotted for the pesse 'e of the intersectting inuiiion -e intersecting muiii-on construct 3. of separate web and fionge'portions assembled *1 W shaped form, the web of the hitter slotted to receive the web of the cross-s1. inuilion the weii at one end of the siotted portion divided whereby. the web may be bent to receive in the siotthe web'of the cross-shaped inuliion said bent web being afterward restored to its riginei condition to embrace the web of the cross-1nui1ion, and in the web portion to which it is subsequentiy welded, whereby continuous und vided tions of each intersecting member alternate jand overlap the other,
